Tessera subsidiary buys 73 MoSys patents

SAN FRANCISCO—Invensas Corp., a subsidiary of technology licensor Tessera Technologies Inc., said Thursday (Dec. 29) it purchased 73 memory chip technology patents from MoSys Inc. for $35 million in cash.

MoSys (Santa Clara, Calif.) retained a royalty-free license to use the patents—which include 43 U.S. patents and 30 foreign patents—as part of the deal, Invensas (San Jose, Calif.) said. MoSys also retained the rights to offer sublicenses to current and future partners, the companies said.

"The MoSys patents are very relevant to industry-standard DRAM products that have been shipping from the fabs of our potential licensees," said Simon McElrea, president of Invensas, in a statement. "The MoSys transaction represents an important milestone in our ongoing acquisition program."

"The combination of the retained license and the non-dilutive source of funding made this transaction very appealing," said Len Perham, MoSys president and CEO.
